PERN - Pakistan Education and Research Network is funded by the Pakistan Higher Education Committee (HEC) and is a nationwide educational intranet connecting premiere educational and research institutions of the country. The network provider for PERN is NTC. The network design consists of three nodal points at Islamabad, Lahore and Karachi interconnected by 50Mbps. Educational institutions are connected by a minimum of 2Mbits/s. All land based Internet connectivity is via the Pakistan Internet Exchange (PIE) in Karachi where the fibres come ashore. PIE in turn is managed by Pakistan Telecommunication Compant Limited (PTCL). PTCL has excess capacity on its long haul international fibers.
Pakistan's sole under sea optical fiber link in 2005, called Southeast Asia, Middle East and Western Europe-3 (SEAMEWE-3), stopped working for about 12 days due to a fault from 27th June to the 8th of July 2005. This disruption halted the global connectivity of almost 10 million internet users in the country. The details can be found here.
Recently Pakistan has connected to SEMEW4 which provides Pakistan with a redundant link in case the outage occurs again. Here is the complete story http://www.pkblogs.com/pakistan/2006/01/smw4-mitigates-total-blackouts.html Here is a case study of Internet connectivity of NUST Institute of Information Technology (NIIT) that was done in 2004 Internet performance for NIIT, Pakistan Jan - Feb 2004 PERN - Pakistan Education and Research Network is funded by the Pakistan Higher Education Committee (HEC) and is a nationwide educational intranet connecting premiere educational and research institutions of the country.

Mobilink has almost completed its backbone and has a submarine fiber link to its sister company TWA which will be the next national media provider after PTCL. This will be the third undersea fibre cable project for Pakistan (SEAMEW3 and 4 are the first two and are operated by PTCL). In February 2007 Telekom Malaysia announced that the company is set to complete its US$100 million countrywide fiber-optic-backbone project in Pakistan - the largest fiber-optic network in the country - by October 2007. The backbone will link more than 75 major towns and cities in Pakistan. The project is with Multinet, a Pakistan ISP that is now a subsidiary of Telekom Malaysia. A fourth company, Wateen is laying out a fiber backbone at a cost of $100M. It appears that all of this investment will provide more options for Pakistani network access.
